(I have also tried adding '-L/foo/lib -lquad' and '/foo/bin' to PATH)
What have I done of wrong?
Hard to tell. Do you have those symbols defined in the libquad shared lib? (You should be able to check using "nm".)
Also, why are you using a static library for libgfortran instead of shared library?
It seems I can build this test case
$ cat test_qp.f90
program test_qp
implicit none
integer, parameter :: QP = 16
real(QP) :: x = 0.124_QP
print *, x,precision(x),digits(x)
end program test_qp
with this workaround:
$ gfortran-4.6 test_qp.f90 -o test_qp
/usr/local/gfortran/lib/libgfortran.a /foo/lib/libquad.a
$ ./test_qp.exe
0.12399999999999999999999999999999999 33 113
